ASME B16.9 45° Elbows (Long/Short Radius) – Buttweld pipe fittings in SS304/316, ASTM A234 WPB and alloy steel. Sizes from 1/2" to 12" with beveled ends.
Bhavani Industries is a leading manufacturer and exporter of premium-quality Buttweld 45 Degree Elbows, designed in compliance with ASME B16.9 and other global standards. Our 45° elbows are engineered for smooth directional changes in piping systems, reducing turbulence and pressure drops. Available in both Long Radius (LR) and Short Radius (SR) types, these elbows are ideal for applications requiring compact layouts or gradual flow transitions. We offer a comprehensive size range from ½” to 48” (DN15 to DN1200), with wall thicknesses ranging from SCH 5 to SCH 160 / XXS.
Our 45 Degree Elbows are manufactured using high-grade materials to ensure strength, durability, and corrosion resistance under extreme conditions. Material options include Stainless Steel (SS 304, 304L, 316, 316L, 321, 347), Carbon Steel (ASTM A234 WPB, WPC), and Alloy Steel (ASTM A234 WP5, WP11, WP22, WP91). Every fitting is produced using advanced techniques such as CNC machining, hydraulic pressing, induction heating, and precision beveling, ensuring excellent dimensional accuracy and welding compatibility.
We adhere to strict quality control procedures to guarantee product performance and reliability. All elbows undergo thorough inspection processes including 100% PMI (Positive Material Identification), Ultrasonic Testing (UT), Radiographic Testing (RT), Hydro Testing, and third-party inspections upon request. Our fittings conform to international standards such as ASME B16.9, ASTM A403, EN 10253, and MSS SP-43, making them suitable for high-pressure, high-temperature, and corrosive service environments.
Bhavani Industries proudly supplies Buttweld 45 Degree Elbows to major industries including oil & gas, petrochemicals, power generation, refineries, and offshore platforms. With a robust export presence across Africa (Nigeria, Kenya, South Africa), the Middle East (UAE, Saudi Arabia, Oman, Qatar), and the USA, we deliver reliable and timely solutions tailored to each client’s project requirements. Our commitment to quality, engineering excellence, and customer satisfaction makes us a trusted name in the global piping components industry.
Global supplier of 45° Elbow LR/SR Buttweld Fittings in sizes ½” to 48”. Available in SCH 10 to XXS. Produced to ASME, MSS-SP, and DIN standards for seamless system compatibility.
